Setup tomato qos skype

Both are exceptional, with DD-wrt having more configuration options settings and Tomato having exceptional QOS configurations. Tomato's QoS is highly configurable and will give you more flexibility than many other routers at even higher prices. The results if properly implemented should produce a better, more stable, higher quality network for VoIP. By creating classifications in Tomato QoS configurations you set rules whereby the router will prioritize certain types of traffic in favor over other types of less important traffic.

VoIP or voice traffic RTP protocol UDP should be set to Highest, as any impediment to its timely delivery will most likely be noticed as choppy voice or bits of voice missing, a totally undesirable outcome.

QoS for more advanced networks can be tricky to set, but Tomato firmware has made initiating QoS settings more somewhat easier with a user friendly interface. Next would be setting the Default class to Low which ensures that the bulk of the unclassified traffic which is not prioritized will not move up in priority over the types of traffic that you do want to prioritize.

This setting creates more or less a lower priority group and then allows you to use specifically designed rules in the Classification settings to define higher priority exceptions. Classification requires identifying and assigning specific types of network traffic to a priority class. For instance you might want Web browsing Port 80 to take priority over other types of traffic and give it possibly a High status.

Classification might include only the significant types of traffic in your network that you want to take priority over other types of traffic. Because bandwidth limitation and network congestion are factors that are always present in a network, we must have QoS configured correctly to optimize the end-user experience.

As QoS can be configured end to end, it's more useful that your media traffic traverse over a Wide Area Network WAN because a Local Area Network might not have the same network congestion and bandwidth issues. With that said, QoS is always required. When the client initiates media traffic using applications like lync. Operating systems such as Windows 10, Windows 8, Windows 8.

This means that all client apps, which utilize the audio, video, and app sharing file transfer ports that are configured for audio, video, app sharing, or file transfer will get DSCP markings stamped. In other words, the Windows or Windows Server operating system can identify the traffic type and apply the appropriate DSCP to each packet according to the port that it uses.

Skype for Business clients for iOS Version 6. This QoS capability is only applicable to Skype for Business clients and IP phone devices which are registered directly to an internal Skype for Business or Lync pool Server on managed networks. QoS is not applicable for traffic routed over the Internet. Application servers and Mediation servers only support QoS for audio. You do not need to change video or application sharing ports in your Application servers or Mediation servers.

Each port type — audio, video, and application sharing — is assigned two separate property values: the port start and the port count. Thus, in our above example, we achieved 42, Kbps for our download bandwidth, and 3, Kbps for our upload bandwidth. Open your web browser and type the IP address of your router into the address bar Usually something like Leave the port set to WAN. Leave the Packet Scheduler and Queuing Discipline set to the default state it should be set automatically based on the router hardware.

Finally, fill in the downlink and uplink values. Multiply both values by 0. Why use a reduced value? Quality of service rules only work if the router and the quality of service algorithm can create an artificial bottleneck to redirect traffic as the QoS handler sees fit. If you use values equal to or larger than the maximum capacity of your connection then you give the QoS handler no wiggle room and the system becomes significantly less effective. Some newer routers have dead-simple QoS options, where you just select the services you want to prioritize them or drag-and-drop them on a list.

Here, for example, is a screenshot from a newer ASUS router we have:. The priority values are:. These values determine the amount of bandwidth allocated to a given application or device.

If you want every device on your network to have priority access to a certain app or service, then you can creative a network wide service priority rule. You can prioritize your local Ethernet network, you can prioritize wireless connections, or you can even set rules that makes guest network traffic a low priority. Interface priority is, because of the requisite knowledge of the arcane network naming schemes, one of the more difficult priority systems to use.

Say you want to give a specific device—like your work computer—priority at all times. If you use static IP addresses or DHCP reservations on your network, you can prioritize traffic on certain computers and devices using their IP address. You would input the address in the Netmask Priority section and append the end with 32, as seen below.

The 32 element is the netmask. Any other smaller number will allow for the mask to encompass a higher number of addresses in a given block e. You can refer to this netmask quick reference guide to select a number that works for the section and size of the address block you wish to prioritize. Now regardless of what IP address your router assigns, say, you can ensure your work laptop it will always get priority.

The best thing you can do to minimize frustration with your QoS setup experience is, as we emphasized above, to take it slow. Set a rule for a big ticket item and then just use your network as your normally would. Does everything run smoother? Things still need a little fine tuning? Return to the QoS control panel. Because of this, if you run a busy network, you've probably noticed that in practice it is actually unable to keep the incoming data pegged low. Heavy traffic on a couple of classes may well exceed the total bandwidth available.

But if we do that - we end up with quite low throughput on some of our classes - they can't use all of the bandwidth. Tomato's QOS is unfinished! Now, these figures we are bandying about are not cast in stone. While a link is busily "stabilizing itself", new connections are constantly being opened by WWW, Mail, Messenger, and especially other P2P seeders, while other connections may close unpredictably, and that upsets the whole thing.

The goalposts are constantly moving! You will see from this that P2P in particular is very difficult to accurately control. Over a period, the average should approximate the limit figures.

Best latency is achieved with a combination of 1 and 2. Juggling them to accomplish what you want is an art. These graphs of the latency of a 1. Now let's add some additional information onto the first graph. You can see that ping response begins to be affected from 1Mbps pwards, even at 1.

Set it only when all else has been adjusted and you can see if your outgoing settings are causing congestion. If you try to set up your QOS with incoming limits set, it will actually make it rather difficult for you to see what is happening as a result of your settings, because the limit will kick in and mask what is going on. Initially, it is useful to set the incoming overall limit to so that it is in effect switched off, this will make things easier for you while examining your graphs and adjusting your QOS parameters.

To recap - For best throughput and reasonable response times and speeds, set incoming class limits quite high if you wish. For best latency, set incoming limits lower.

If your router crashes or becomes unstable due to P2P applications opening large numbers of connections, try to limit the number of ports that a user can open. Check that function before adding another rule.

You may list the iptables rules by telnet to the router and issuing the command "iptables -L" ["-vnL" for verbose output] or "iptables -t nat -vnL". If you are running a recent tomato mod, you can also do this from the "system" command line entry box, which is much more convenient. Now an explanation. This therefore places a limit on the connections to the outside from each client on your network.

Without this limit, the router can still be overloaded by incoming P2P etc. Placing limits into either of these chains, which is usually recommended, does work , but in the event of a "real" DOS attack or SMTP mail trojan, the router often instantly reboots without so much as a single entry in the logs.

Following much investigation and discussion with phuque99 on Linksysinfo. The router seems to stay up and running. The next script is to prevent a machine with a virus from opening thousands of connections too quickly and taking up our bandwidth. I don't like this much, because it can prevent a lot of things working properly. Use with caution and adjust the figures to suit your setup.

NOTE If you test the above scripts with a limit of say 5 connections in the line, you will often see that it doesn't appear to be working, you will have many more connections than your limit, maybe , that you can't explain. Some of these may be old connections that have not yet timed out, and waiting for a while will fix it.

You should disable it on your PC by command line:. If your router becomes unstable, perhaps freezing or rebooting, apparently randomly, then it may have been asked to open too many connections, filling the connection tracking table and running the router low on memory. Often this can happen because poorly behaved applications usually P2P clients can attempt to open thousands of connections, mostly UDP, in a short space of time, just a few seconds.

The router often does not record these "connection storms" in the logs, because it runs out of memory and crashes before it has time to do so. Obviously, there is a flaw in the firmware, which most definitely should never allow this situation to happen. Until such time as we can correct this situation, we must resort to some means of damage prevention and control.

Setting the number of allowed connections high say makes the situation worse. In fact this number is almost never required. Most connections shown in the conntrack page will actually be old connections waiting to be timed out. Leaving the limit low, say to connections, gives the router more breathing space to act before it crashes.

The following settings have been found to help limit the connection storm problem somewhat, without too many side effects. Use the smallest number that is reliable.

Background The author has been involved in setting up WiFi in several large residential blocks, where it was important that the result not only worked but was simple to maintain by reception staff.

QOS in operation — is it effective? But someone has to define a set of QOS rules for a particular environment. That's YOU! Time to really get down to business… Let us have a look to see why many people fail to get QOS to work properly or at all, especially in the presence of large amounts of P2P.

We are left with two points commonly responsible for bottlenecks. Bottleneck No. Let's go back for a moment to the analogy in the introduction: Suppose there are a thousand people out there who will send you letters or parcels in the mail if you give them your address and request it. Reducing outgoing traffic for a class.
